PNEUMATIC-TIRE PROTECTOR.

Application 'fiiea March 17, 1922. Serial No. 544,593.

pneumatic tire 1,275,199, granted Aug. 13, 1918 in that itwill'be moreflexible for yieldingwith the tire, in which the parts willhavesubstantially frictionless movement, and in which the parts areextremely substantial, durable and capable of being hooked to the rim ofthe tire.

become apparent from a consideration of the description following takenin connection with the accompanying drawings illustrating one practicalembodiment.

In said drawings v Fig. 1 is a View in perspective showing myimprovements associated with a tire and run fragmentarily; 1

Fig. 2 is a cross sectional view on the line 22 of Fig. 1;

F 1 3 is a deta l perspective of one of the side Ieaves employed;

Fig. 4 is a detail perspective view of'one of the tread plates employedand Fig. 5 is a detail perspective view of one of the hook leavesemployed.

Like reference characters designate like or corresponding parts in thedifferent views. V I

By way-of example, a tire shoe or casing is shown at A mounted in theusualchannel rim B and having the usual pneumatic tube C. Thisconventional representation will illustrate the practice of theinvention. a The invention consists of a tread plate or 5 leaf 10 andside plates or leaves ll, preferably a plurality on each side thereof,and anchoring or securing plates 12. These plates are adapted to beconnected together by pivot rods such as 13 which pass through barrels14 on some of them and'lugs 15 on some of them. The plate 10 merely hassuch lugs 15 at each side Plates 11 at one side have one of the barrels14 and at the other have the lugs 15. Plates 12 merely have one of'thebarrels 14. The barrels 14 Additional objects and advantages will Iinterfit between the lugs seen in Figs.

1 and2.

On the plates 12, bars 16 are provided which serve as hooks or anchorsto hook detachably over the side edges of the rim B for dispositionintermediate the rim and shoe A to retain the protector in place.

Theprotectors are employed in any desired number about the tire and atread of any suitable design as at D is preferablyv retained b theplates 10, through the medium of suitable side flanges at 17. Theparticular mounting means of the tire of course i is immaterial and a,limitation'to the same 7 as shown is not to be inferred.

Attention is called to the fact that the different platesarebodilycurvedto conform to the tire and that the plates 11 may I bereinforced as at 18 when desired.

A very important feature resides in the anti-friction connection of theing rods or rollers 19-are disposed about the rods 13. In orderto'maintain the rollers plates. I/Vithin each barrel 14,, a plurality ofhea 19 within the barrels without possibility of 13, and that suchplates protect the tire.

As merely one practical embodiment hasv 1 been illustrated anddescribed, it is to be be made within the spirit and scope of theinvention as defined by the appended claim.

I claim as my invention A tire protector consisting of a plurality ofplates to surround the tire, anchoring hook flangeS'eXtending from twoof said plates, certain. of said plates having lugs,

certain of said plates plates having barrels to fit intermediate saidlugs, disks interpa ssing through saidlugs, barrels and disks, andbearingmembers in said barrels to abut said disks at the ends of thebearing members. 1

In testimony whereof I aflix my signature. CHARLES W. BAIN. 7
